This invention relates to an apparatus for two-dimensional electrophoresis which comprises a supporting plate fixed to a rotary axis, a support for first dimension electrophoresis disposed on the supporting plate and a support for second dimension electrophoresis disposed on another supporting plate. Both the supports are arranged in such a fashion that when the rotary axis is rotated, the support for the first dimension electrophoresis comes on the support for the second dimension electrophoresis or reaches a predetermined position in the support for the second dimension electrophoresis. This arrangement can shift the support for the first dimension electrophoresis to the support for the second dimension electrophoresis without damaging the former.

Apparatus for two-dimensional electrophoresis

A horizontal electrophoresis apparatus characterized by a cooling plate which consists of a sintered SiC with high thermal conductivity and good insulating properties, or sintered material composed mainly of SiC, and a Peltier element, as the heat conducting material to cool the supporting matrix or electrolyte.

Electrophoresis apparatus

A nephelometric immunoassay and a nephelometer therefore, characterized in that light is projected on a sample to-be-measured containing an antigen-antibody complex, that at least two light scattering intensities at different angles with respect to the incident light are measured, and that a true antigen concentration is discriminated by comparing the light scattering intensities.
